hsp-60 | mim-stimulation | WBInteraction000502398 (WormBase) | RNAi knockdown of dve-1 prevents expression of a Phsp-60::GFP reporter transgene in response to the zc32 allele at 25 degrees Celsius, spg-7 RNAi, or exposure to Ethidium Bromide (all known to induce UPRmt and, hence, hsp-60 expression). dve-1 RNAi also disrupts induction of endogenous hsp-60 expression induced by spg-7 RNAi, as determined by QRT-PCR. ubl-5 RNAi results in diminished expression of an hsp-60::GFP reporter and endogenous hsp-60. | |
hsp-6 | mim-stimulation | WBInteraction000520482 (WormBase) | ubl-5 RNAi results in diminished expression of an hsp-6::GFP reporter and endogenous hsp-6. dve-1 RNAi also disrupts induction of endogenous hsp-6 expression induced by spg-7 RNAi, as determined by QRT-PCR. |
